KORONADAL CITY, Philippines — Criminal cases have been filed against an alleged leader of the El Patron drug ring, touted as the largest narcotics syndicate in South Cotabato province.

Gil Castro, director of the Philippine Drug Enforcement Agency-12, said Wednesday that Ruel Lalisan Espinosa, arrested in Koronadal City on Monday, has been charged with violation of the Comprehensive Dangerous Drugs Act and illegal possession of firearms and a rifle-propelled grenade.

“The cases were filed against him on Tuesday. We are thankful to the vigilant people who secretly helped us locate him,” Castro told The STAR.

Combined police and PDEA-12 agents found in Espinosa’s hideout in Barangay Santo Niño here P500,000 worth of methamphetamine hydrochloride (shabu), two M4 assault rifles, a .45 caliber pistol and a live grenade.

Castro said their operation on Monday was assisted by the Army-led anti-crime Task Force GenSan and members of the police Special Action Force.
